COMPANY, A CORPORATION OF NEW APPUANCE FQR FEEDENG BRUSH-BLOCKS- No. 855,81 1; Specification of Letters Patent. Patented June 4, 1907.

Application filed December 20, 1905. Serial No. 292.658.

To aZZ whom it may concern:

Be it known that we, MARTIN O. REHFUss, of 1417 South Broad street, Philadelphia,

county of Philadelphia and State of Pennsyl- 5 Vania, and EDWARD F. BUCH, of Broadway and Academy streets, Astoria, county of Kings, and State of New York, have invented certain new and useful Improvements in Appliances for Feeding Brush-Blocks, fully de I i o scribed and represented in the following specification and the accompanying drawings,

forming a part of the same. i

he present invention relates to means for feeding the brush-block in transverse and loni5 gitudinal directions to present it automatic-- ally to suitable drilling or tufting devices, so that tuft-holes may be drilled in the brush* block, or tufts inserted at regular spaces in rows,- and the rows also suitably spaced apart upon the block.

S ecial devices for drilling and tufting the 'blocis are shown in the annexed drawing, but I are not described in detail nor claimed herein as such particular devices are made the ectof a separate application, N 0. 292,657 filed December 20, 1905 and entitled Ma chine for drilling and tufting brushes.

The present appliances for feeding brushblocks embrace a brush-block holder which sustains the brush-block, a rock-shaft journaled beneath the drilling and tufting devices, a carrier for the block-holder pivoted l at the axis of the rock-shaft, rocker-arms carried by the rock-shaft, a control-shaft 5 movable lengthwise in the rocker-arms and I exte" d through the holder and jointed to l e, a control-cam suitably actuated to e control-shaft longitudinally after the drilling or tufting or" each hole in the block, and a rocker-cam actuated twice during each revolution of the control-can1, so as to shift the rocker-arms and move the block laterally, at the alternate-ends of the rows, to space the same.

A cam-shaft is shown in cpnnection with the drilling and tufting appliances, and a driving-cam is shown upon the ear which turns such camshaft for suitab y turning the control-cam to actuate the brush-feeding 5o appliances.

he inventlon consists 1n the features'of which will construction hereinafter claimed,

be understood by reference to the annexed drawing, in which I Figure 1 is a plan of the machine with the block-holder omitted and the frame broken away where it carries the tuft-feeding appliances, and two clutch-hubs'with thepart of the shaft which supports them are shown in dotted lines to expose the clutch-levers which lie normally below them. Fig 2 is an elevation of the front end of the machine; Fig. 3 is an elevation of the right hand side; Fig. i an elevation of the left hand side; Fig. 5 is a longitudinal section, where hatched, at the center line of the brush-block holder; Fig. 5- is an elevation of a construction alternative to Fig. 5; Fig. 6 is an elevation of the block-carrier and lockingdevice, in cross section, where hatched, at the center line of the brush-block holder in Fig. 5; Fig. 6 shows the under side of the gage-plate; Fig. 7 is a cross section on line 77 in Fig. 1,- Fig. 8 is a cross section on line 88 in Fig. 1; Fig. 9 is a cross section cnline 9-9 in Fig. l; and Fig. 10 isaside elevation of the control-cam, its ratchet-wheel and hand-wheel with their connecting sleeve. Fi 11 is an elevation of the clutch and clutch lever for the shaft 0; Fig. 12 is an elevation of the clutch and clutch-lever for the shaft 6; and Fig. l3 is a perspective View of the parts forming the clutch-control for the shaftc.

' The machine is shown with a bed a having frame b to support the tuftingand drilling appliances which are carried upon the top of such frame ,A driving-shaft c is mounted in bearings c upon the bed and'provided with a pulley c turning loosely upon the shaft between the outer hearing 0 and clutch-hub c, which is shown in dotted lines in Fi 1 to expose the clutch fixtures below it. i clutch-bolt d is fitted to slide through the clutch-hub c and when engaged with a notch in the hub of the pulley c the motion 01' the pulley is transmitted to the driving-- shaft; forming a well known detachable press-clutch in which the bolt is pressed normally into the notch by a s iring; the spring not being shown in the (i such press-clutches are already wellknown. A clutch-lever d is provided with a slo ing face to engage the head of the clutch ho t d, and When'the lever is pressed against rawing as the side of the clutch-hub it retracts the bolt from the pulley and arrests the drivingshaft. The lever d is mounted upon a shaft (1 provided with a s rin d? to ress the lever normally toward t e c utchub c, and a latch (1 serves when engaged with a stud d to hold the clutch-lever ino erative until the completion of the brush dri ling operation as hereinafter set forth. (See Figs. 1 and 2'). A cam-shaft e is mounted in the bottom of the frame I) and connected with the drivingshaft 0 by gears e and c the gear e being fitted to turn upon the shaft between a bearf therewith are the following cams: The tuftering f and a clutch-hub 9 ,The hub g is attached to shaft 6 and'is'provided with a clutch-bolt g which is controlled by a clutchlever 9 The clutch-lever g is mounted upon a shaft g 'and pressed normally away. from the clutch-hub g by a'spring 9 (See Fig. 4).

- Attached to the cam-shaft e to rotate feed reciprocating means, which is not herein claimed 01" described indetail, is operated by the cam h at the rear end of the cam-shaft; the clutch-lever g is moved'at intervals in opposite directions by a cami and also by a connection to a gage-plate in the blockholder, as hereinafter described, to stop the drill and tuft-driver at the ends of the rows, when tufting oval. brush-blocks; the tuftpIacer is operated by the 'cam j;- the tufter and boringhead reciprocating means by the cam 7c; the tuft-inserting means by the cam l, and the boring means by the cam m. The cam i will be described in connection with the brush-block holder, and th'e connections from the cam j need no detail descri tion herein. The cam k operates throu. h lever k to reciprocate a slide n horizontal y in the top of the frame 7), such slide carrying a head 0 in which a drill p and tuft-driver q are movable vertically; the movement of the slide n' shifting the head 0 so as o bring the drill p and the tuft-driver alternately over the same point in the brush-block r. The cam l operates through a bellcrank Z to reciprocate the tuft-driver q, and the cam m operates through bell-cran'k m, link m and levers m to reciprocate the spindle s of the drill p. i

The mechanism driven-by the shaft e is not claimed herein, but is referred to because the block-holder feeding-means is operated alternately therewith;

I Bloclc holder feeding-means. A drivingcam .t which operates this feeding-means is attached to the gear-wheel e to revolve therewith; and it thus continues to operate the feeding mechanism when the shaft e is stopped, which occurs by the automatic retraction of the clutch-bolt g at the ends of the rows of tuft-holes when tufting ovalv brushes, as hereinafter described The cam t, by means of an arm'u, oscillates a rock-.

.beneath its lower end in Fig. 9.

shaft a which reciprocates a link a to 'vibrate a pawl-arm u The pawl-arm carries a pawl "a fitted to-the teeth of a ratchet-wheel q) which revolves around a shaft o The ratchet-wheel is attached to a sleeve 12 to revolve with a so-called control-cam w. The shaftv is supported in bearingsw and the sleeve 0 is extended through the outer bearing w and provided with a hand-wheel 112 to turn the control-cam by hand.

The control-cam has a double inclined slot in its periphery, and a pin ac is fitted to such slot and is carried by a slide as. The pin is fitted-movably in the end of a control-shaft adwhich is jointed to the block-holder (1: The in x moves'the control-shaft to effect the ongitudinal spacing of the tuft-holes. The control-shaft 00 is given a lateral movement, to effect the lateral spacing, by a link at? which is intermittingly moved by a rockercam 20 attached to a sleeve 2 with a rocker tooth-wheel y, and said sleeve attached to the shaft o so that both revolve therewith. The link carries a pin 1 which is extended into an eccentric slot in the cam and the pin is supported m'ovably by an arm 2 jour- Iialed in a bearing upon the bed, by a pivot 3.

Over the shaft v? a pawl-shaft 5 is mounted upon the standards of the bearings w, and carries a detent v for theratchetwvheel 12C.

(Fig. 7.) Attached to one end of the cam w a is a pawl-cam 6 with projections at opposite sides of the center to oscillate the pawl-shaft. The pawl-shaft has two arms, one carrying a roll 7 to bear upon the pawlcam 6, and the other arm carrying a pawl z to actuate the tooth-wheel y. The teeth on wheel 1 are indicated only by dotted circles in Fig. 8'. A s ring 9, shown upon the end of the pawls aft in Figs. 1 and 2, is provided to move the pawl to turn the tooth-wheel y when it is required to actuate the rocker-cam 90 The cam 6 aflects the rocker-cam as twice in each rotation of the cam w. Upon the lower side.

of the tooth-wheel y, a spring-bolt y isd rovided to engage the tooth wheel, and is pressed toward the wheel by a spring shown A bolt spindle y is mounted adjacent to the locking-bolt, and arms y are attached thereto,

pin and slot as 'shown in Fig. 9, while the other arm carries a roll 8 to contact with the two projections upon the pawl-cam 6, as shown in Fig. 8. p

The rolls 7 and 8 are so arranged in relation to the o )posite projections of the cam 6, that when the cam is rotated, as shown by the black arrow 1.0 in Fig. 8, the locking-bolt is first retracted, and the pawl-shaft 5 then actuated to retract the pawl 8. The assage of the cam beyond the roll 7 releases t e awl 2, and the spring 9 then moves the paw arid turns the cam y in the reverse direction,in-' dicated by the dotted arrows in Figs. 7 and 9.

I15 and one of them connected to the bolt by a block applied to ter' when formed by a eaten The movementof the wheel one tooth partially rotates the earn at, which operates upon the pin to move the link Thecontrolshaft is thus mcvedlaterally byithe, rocker cam and longitudinally by the controlcam 20 r r The control-shaft is jointed to the carrier 11 of the block-holder 00 which is formed with a fulcrum-ball 12 at its lower end mounted in a bearing-block beneath the drill and tuft-driver. A rockshaft 14 is shown in Fig. 5 extended through the axis of the bearing-block, and rockerarms 15 extended from the same to the control-shalt Spherical segments 16 are shown fitted to the sides of the carrier 11 and cups 17 attached to the control-shaft to embrace the same, which permits the carrier to tip upon the bearing b'lock when the controlshaft moves lengthwise. The rocker-arms 15 are rigidlyattached to the rock-shaft 14 and thus hold the control-shaft successively in parallel positions when thelink :1: is inter-- nnttingly actuated by the earn 1/.

The control-shaft sli s through the rockerarms when moved by the cam w, and the cam is thus ada itedto rock the brush-block laterally and longitudinally, so as to make the tuft-holes 23 incline outwardly from the cendrill. 4

The rocker-arms 15 with the controlv 1 shaft movable lengthwise through the same,

.forms the simplest mechanism for giving to the brush-holder the inclination in two directions upon: its universal joint. The essential nature of thisiinotion and the operation of the arins and control-shaft to produce it, is illustrated'in Fig. 5 where the mechanism is shownniore simplified by jointing the carrier 11 directly upon the rock-shaft 14 and forming a slotted connection between the carrier and the-control-shaft it". While this mechanisni'is simpler than that shown in Fig. 5, it is not preferred, as it does' not'afl'ord the means of coinpeiisatingior wear'or taking up lost motion like the globular joint uponthe control-shaftand the; divided bearingv theball 12 upon the bottom of the carrieiuJ f= I The block-holder,afi'is mounted upon the carrier :11 by..:slianlis- -18; rvh'ich penetrate sockets 19 in "carrier" 'aind'are provided with col-larsQU to rest up'on'springs 2i fitted" within or'r lrets' to support-the blockthe sockets over the collars,

Locking of block-holder. To look the brush-holder in position 'for drilling each hole exactly in the ently of the shifting effected by the rockercam and control-cam) a ga e plate 24 hav ing holes or recesses 24 is. fitted withinthe top of the hollow block-holder, and a lockingpin 25 to engage the said holes is en ported in a socket upon an arm 26 rojeete within proper place (independ;

the block-holder which ho ds the lockingpin in a direct line beneath the drill-when drilling'a hole. The pin requires to be retracted before each movement of the bloc'kholder, and this is effected by the 'operation'of thecami. ing-pin is pivoted upon the'arm 26 and connee-ted by a link 28 with the rock-shaft'g cam t is formed as a projection uponithe side of the Cylindrical cam y' and operates upon an arm 29 attached to the shaft 9 upon the shaft 9 presses the arm 29 normallyagainst the cam i and also presses the lockin pin normally into the holes of the A lever 27 which ac'tuates the lock- The spring 9* y gage-p ate. 'The" movement of retracting the lockin pin from the holes by the cam i operates a; so to ward the clutchrub 9, but does not actuate the clutch-bolt g, which loes not move in proximity to such clutch-lever when the cam z operates upon the arm 29. This is clearly shown in Fig. 13, where the clutch-lever is ing adapted for an oval brush-block, in which the lateral rows are shorter than the middle rows.

The slot in the cam w moves the controlress the clutch-lever 9 to- IOO ' pressed upward to the hub, whilethe clutchshaft 9: so ,as to oscillate the brush-block uniformly, and if the drill were operated after ach step-by-step movement of "the control-shaft; the rows of tuft-holes would all be of uniform length; but the absence of "holes in the gage-plate at the ends of the shorter rows, prevents the locking-pin from "making its normal'movementand thusfholds the clutch lever g in the path of the locking- I bolt, andretra'cts the bolt from the gear 6;

thus stopping the drilling and tufting shaft e until the intermittent movements of the brush-h0lder again bring one-of the holes in line with the locking-pin. The penetration of the pin into such hole then operates to retract the clutch-lever from the clutch-bolt which again enga es the rotating clutch-hub g, and causes the r rilling and tuftin mechanism to operate. The movement 0? the drill is thus controlled by the gage-plate, and the holes may therefore be drilled and tufted in any desired pattern upon the brush-block, although the block may be movegl farther at each complete rotation of the control-cam than the length of the row that is drilled and tufted, the drilling and tufting devices being arrested at the ends ofthe row.

Operation-0f the machine. With the latch (1 hooked upon the stud (P, the rotation of the shaft 0 operates to turn the cam-shaft e and actuate the drilling and tufting appliances.

The cam t at the same time operates the rock-shaft u and the pawl v, thus turning the control-cam to sufficiently, at each actuation of the tufting devices, to shift the control-shaft and block-holder longitudinally, to space the holes and tufts in the rows upon the brush-block.

The cam w is so set in relation to the projections upon the cam 6, that when the block-holder is carried by the pin cc and control shaft w to either end of its longitudinal movement, the earn 6 operates the pawl 2 and slightly shifts the tooth-wheel y and the rocker-cam ac, which shifts the control-shaft and the block-holder laterally to drill an adjacent row. The cam 'i is so disposed as to retract the pin 25 from the holes 24' in the gage-plate of the block-holder, prior to such actuation of the cams u and a, and so long as the holes in the gage-plate are opposed to the pin to permit the pins normal movement, the clutch-lever g is held from contact with the clutch-bolt g and the drilling and tufting continues intermittently.

At the ends of the rows, where the holes are omitted, as with the oval design shown in Fig. 6, the movement of the pin is interrupted, and the clutch-lever g is held against the clutch-hub 9 throughout anentire rotation of the gear 2', which brings the clutchbolt 9 in contact with the inclined face upon the lever and stops the clutchhub and the cam-shaft e from further rotation. The gear e continuing to revolve, the cam t continues the actuation of the block-holder feedingdevices, which soon brings another hole in the gage-plate opposite to the pin 25, which permits the s ring 9' to turn the shaft 9 and retract the c utch-lever g from the clutchhub g. The bolt y then automatically reengages the gear 2, and connects the shaft 6 therewith and renews the drilling and tufting movements.

Several .of such automatic machines may be managed by one operator, who secures the brush-blocks upon the block-holders, and engages the latch (1* upon each, with the stud d so as to hold the clutch-lever d inby one group of devices actuated b ing operation. automatically, when the tufting of the brush:

block is completed, by a pin 30 movable with operative throughout the drillingiand tuft I Each machine as stopped menced with the block-holder tip' (1 in-- wardly toward the frame of the mac e, as indicated by the dotted lines 0: in Fig. the block-holder at the conclusion of the drilling movement is therefore tip ed outwardly as indicated by the dotte in Fig. 9, which brings the pin 30-inl1newith the arm 31 upon the late movement, as indicated in Fi 9, the pin contacts with the arm 31 and disc ages the latch from the stud cl, thus ermittmg the spring (1 to throw the clutc-lever (1' into the path of the clutch-bolt-d which, when enga ing the inclined face (1 uponsuch clutc -lever, is retracted from the drivingpulley 0 This stops the driving-shaft c and the entire machine.

The re-engagement of the latch cl with the stud (1 serves at any time to retract the clutch-lever d from the hub and re-connects the drivingulley with the shaft 0. The block-holder ee'ding means thus operates automatically from the commencement of drilling each block; but to rovide for any special adjustment of the b ock before or' during the drilli the hand-wheel w is provided, which ena ice the operator by'turning the control-cam w to shift the blockholder longitudinall' to the end of, or to any 6-and lines :6.

and when the block-holder reaches its extreme left handpoint in, the row 0 tuft-holes. The blockholder may be set sidewise by hand, by means of handles shown upon the pawl z and rocker-cam 11: in Fig. 9, the pawl being lifted from the tooth-wheel y, and the cam then oscillated, to move the block-holder laterally into any required, position. Such manual adjustments permit the shifting of any hole in the brush-block from beneath the drilling and tufting appliances for removing a defective tuft,and then restoring the-hole to its previous osition for retufting. I From the a ovedescription it will 'be seen that the drilling and tufting is efiectpld t e cams upon the shaft e; while the feeding of the brush-blocks is effected by another group of devices actuated by the cam t u n the gear e, and that the cam-shaft e is automatically disconnected from the gear e when the brush-block tufting mechanism is required to discontinue its -movements at the ends of the rows of tuft-holes.
